For applications where fire resistance is a requirement and space limitations prohibit the installation of rigid ducting, our fire retardant flexible duct is an excellent alternative.

Composed of an inner duct of woven, coated fiberglass, permanently bonded to a coated, steel wire helix, a flexible air seal is established. Next, an insulating blanket of fiberglass is added and then an outer vapor barrier of aluminum/polyester laminates. The end product is our fire retardant flexible insulated ducting.

An outstanding solution when cabin units need to provide heating as well as cooling or to route dryer exhaust ducting in laundry rooms. It can be used in high, medium and low pressure HVAC systems.

Its unique construction will not unravel when cut and all components are self-extinguishing and will not support flame.
